PIVOTAL COOLING CAR Filed Sept. 10, 1928 Patented June 11, 1929.

ALBERT I. GROI-IENS, OF MARSHALL, MICHIGAN.

PIVOTAL COOLING GAR.

Application filed September 10, 1928.

This invention relates to improvements in cooling cars, and more especially a pivotal cooling car, here shown as adapted for use for cooling hot roasted coffees and similar cereals and products.

One of the features of my invention is to provide a cooling car which will permit the product contained therein to be cooled while the car is in motion. By means of this construction, the cooling of the product may be commenced as soon as it is poured into the car from the roaster and continued without interruption while the car is moving away from the roaster.

My improved car is also durable, and simple in construction and operation.

Other features and advantages of my invention will appear more fully as I proceed with my specification.

In that form of the device embodying the features of my invention shown in the accompanying drawings, Fig. 1 is a vertical section view, and Fig. 2 is a View taken as indicated by the line 2 of Fig. 1.

As shown in the drawings, there is provided a square hopper-shaped body having sides a, formed of three stationary sides and a door a and having a perforated false bottom Z) to provide an air chamber 0 below. The body is mounted on a truck cl, adapted for circular movement on the wheels e.

As here shown, the body is of the tilting type, but it is ObVlOHS that the same may be stationary if desired. The tilting is accomplished by mounting the body on the shaft f and there is provided, attached to this shaft, the usual operating lever f The truck cl also carries another air chamher or box 9, which is removably connected to the air chamber 0 by means of the collar 71, which projects into the air chamber 0.

The truck (Z is held by a shaft 2', which is pivoted in a stationary floor standard A plate with a round collar 70 is mounted on top of the air-box over the shaft 2' and centered therewith. This plate has a round opening inside of the collar to admit air from the air-box g.

A round pipe Z is loosely hung over the collar k so that the collar is free to turn inside. This pipe is securely attached to another overhead vertical pipe mby means of a clamp or coupling a, the vertical overhead pipe m being suitably connected with a suction-fan (not shown).

Serial No. 304,973.

The pipe m is provided wit-h a circular cover 0, which is rigidly supported from the stationary ceiling-plate p by means of the shaft 9, the latter being secured in the ceiling-plate and the cover-plate o by means of the set screws 1'.

The wheels 6 are set on a circle drawn with a radius from the center of the pivot shaft 2', so that the car is free to turn around the axis of said shaft, the latter pivoting in the floor standard 7', while the pipes Z and m. remain stationary. The collar is in the pipe Z permits such circular movement of the car without disturbing the air connection.

In the operation of the device, the hot roasted material may be dumped from a roaster into the body of the car and the air suction immediately started. Air is drawn through the material and out through the perforated bottom, thus cooling the contents of the car. While this cooling process is going on, the car may be moved away from the roaster in its circular track.

When the material has been cooled, the body of the car may be tilted on the shaft f by means of the lever f and the body emptied by opening the door a In the construction here shown, the tilting of the car body is adapted to separate the air connection between the chambers c and g by lifting the car body off of the collar h.

lVhile I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction, arrangement and operation may be made without departing from the spirit and scope of the invention disclosed in the appended claims, in which it is my intentionv to claim all novelty in my invention as broadly as possible, in view of the prior art.

Vhat I claim as new, and desire to secure by Letters Patent is:

1. A substantially vertical exhaust pipe; a truck adapted for circular movement about the exhaust pipe; a body on the truck having a false bottom with an air space beneath said bottom; and an air conduit between said air space and said exhaust pipe, said conduit being pivotally attached at one end to said exhaust pipe to permit circular movement of the truck around the exhaust pipe.

2. A substantially vertical exhaust pipe; a truck adapted for circular movement about the exhaust pipe; a tiltable body on the truck having a false bottom with an air space beneath said bottom; and an air conduit between said air space and said exhaust pipe, said conduit being pivotally attached at one end to said exhaust pipe to permit circular movement of the truck around the exhaust pipe.

3. A substantially vertical exhaust pipe; a truck adapted for circular movement about the exhaust pipe; a tilt-able body on the truck having a false bottom with an air space beneath said bottom; and an air con duit between said air space and said exhaust pipe, said conduit being pivotally attached at one end to said exhaust pipe to permit circular movement of the car around said exhaust pipe, tilting of the car body being adapted to break the air connection between said air space and said air conduit.

at. A substantially vertical exhaust pipe; a truck adapted for circular movement about the exhaust pipe; a body on the truck having a false bottom with an air space beneath said bottom; and a substantially horizontal air conduit carried'by the truck and having one end attached to the air space in the body and the other end pivotally attached to the exhaust pipe to permit circular movement of the truck around the exhaust pipe without breaking the air connection between said air space in the truck body and said exhaust pipe.

5. An exhaust pipe having an opening therein; a truck adapted for circular movement about the opening in the exhaust pipe; a body on the truck having a false bottom with an air space beneath said bottom; and

an air conduit connecting said air space and said opening in said exhaust pipe, said conduit having pivotal attachment at one end to the opening in the exhaust pipe to permit circular movement of the truck around said opening in said exhaust pipe.

6. An exhaust pipe having an opening therein; a truck adapted for circular movement about the opening in the exhaust pipe; a iiltable body on the truck having a false bottom with an air space beneath said bottom; and an air conduit connecting said air space and said opening in said exhaust pipe, said conduit having pivotal attachment at one end to the opening in the exhaust pipe to permit circular movement of the truck around said opening in said exhaust pipe.

In witness whereof, I hereunto set my hand and S82 1 this 80th day of August. 1925.
